O Clostridium O All of the choices are correct QUESTION 28 The short, numerous appendages used by some bacterial cells for adhering to surfaces are called O flagella. O cilia. fmbriae. O periplasmic flagella (axial filaments) O sex pili QUESTION 29 Archaea do not have the typical peptidoglycan structure found in bacterial cell walls O True O False QUESTION 30 The outcome of the Gram stain is based on difflerences in the cels O ribosomes O inclusions O cell wall O cell membrane. O flagella. QUESTION 31 lodine is the decolorizer in the Gram stain O True QUESTION 32 The most immediate result of destruction of a celfs rnibosomes would be O matenal would not be able to cross the cell membrane O protein synthesis would stop O destruction of the cell's DNA formaton of glycogen inclusions O loss of capsule

Explanation / Answer

27. The answer is A. Staphylococcus.

Explaination:

The Bacillus, Clostridium and Sporosarcina are the examples of endospore producing bacteria whereas staphylococcus is not endospore producing bacteria.

28. The answer is C. Fimbrae.

Explaination:

The short, fine, hairlike bristles that aid in adhesion in prokaryotic organisms are called fimbrae.

29. The statement is True.

Explaination:

Archaea do not have peptidoglycan membrane. It is present in the almost all bacterial cells which are gram positive and gram negative.

30. The answer is D. Cell wall.

Explaination:

Gram positive bacteria cell wall contain thick layer of peptidoglycan with techoic acid whereas gram negative cell wall contains thin layer of peptidoglycan.

31. The answer is false.

Explaination:

Iodine is not used as a decolorizer. It is used as Aa mordent in gram staining.
